<p>PURPOSE:To simplify mounting works by making No.1 surface which is turned to be a roof surface side, large in area, making No.2 surface small in area, and thereby allowing No.3 surface and No.4 surface which are located between No.2 and No.2 surface while side surfaces are being formed, to form respective angles tilted against No.1 surface mutually to the opposite direction. CONSTITUTION:A roof unit 2 is formed into a trapezoid having No.1 surface 3 through No.6 surface 8, No.1 surface 3 through No.4 surface 6 are extended to the longer direction which is to be the ridge direction of a residence, so that No.5 surface 7 and No.6 surface 8 are made to be the end faces normal to the ridge direction. In this case, No.1 surface 3 is made large in area, No.2 surface 4 which is opposite to but parallel with No.1 surface 3, is made smaller in area than No.1 surface, and No.3 surface 5 and No.4 surface 6 are tilted against No.1 surface to the opposite directions while the angle of theta1 and the angle of theta2 are formed respectively. In the second place, the connecting section 11 for 2 roof units which are disposed face to face in the tie- beam direction, is made to be the ridge 9 of a roof 1, and the water proof treatment is then processed with the ridge 9 covered with a member such as a ridge cover and the like. By this constitution, the connecting section can thereby be reduced in number.</p> |
